Yes, at least for current releases.

You can use multiple processes.  A second process can just do select()
on the file descriptors of interest and send SIGIO or another signal with
kill() when appropriate.  Various other approaches are possible; that
one looks the most like SIGIO on the series 800 and BSD.
